As an alternative to SLEEP, use PAUSE. A process in PAUSE will return the call stack via PORT.STATUS.
SLEEP, CALLC, PCPERFORM, and waiting on a record lock are some of most common conditions which will not return a call stack via PORT.STATUS.

We do use signaling to 'interrupt' the running process and get it to tell the PORT.STATUS session what it is up to. IIRC, we use SIGUSR2, specifically. So - there could be some system calls that the udt process is in that cannot be interrupted. For instance, I tested a phantom that was running 'SLEEP 120' - and experienced the same result as Bill (no call stack printed). I changed this to a loop FOR 120 that was printing a line, then SLEEP 1 Here is the result: :LISTUSER Licensed(UDT+CP)/Effective Udt Sql iPhtm Pooled Total ( 32 + 32 ) / 64 2 0 0 0 2 UDTNO USRNBR UID USRNAME USRTYPE TTY IP-ADDRESS TIME DATE 1 5372 305730 WTerhune udt pts/1 Console 11:53:11 Apr 02 2010 2 6020 305730 WTerhune phantom pts/2 Console 11:58:05 Apr 02 2010 3 2384 305730 WTerhune udt pts/3 Console 11:55:11 Apr 02 2010 :PORT.STATUS PID 6020 CALL.STACK Licensed(UDT+CP)/Effective Udt Sql iPhtm Pooled Total (32 + 32) / 64 2 0 0 0 2 Udtno Pid User UserType Port Last command processed 2 6020 WTerhune phantom 8443624 level line BASIC callstack 1 4 BP\_WWW Session no command stack. : Wally Terhune U2 Support Architect Rocket Software 4700 S.

Using LISTUSER() I can figure out what processes are phantoms but not what they're running. Thus, I have no way to figure out of my BACKGROUND.SERVICE program is running (it sleeps and wakes up every minute). When I do a PORT.STATUS PID {pid# of phantom} CALL.STACK nothing is returned (and it takes about 15 seconds on a fast, development system). 2 Dev (0)-> LU Licensed(UDT+CP)/Effective Udt Sql iPhtm Pooled Total ( 24 + 1 ) / 25 3 0 0 0 3 UDTNO USRNBR UID USRNAME USRTYPE TTY IP-ADDRESS TIME DATE 1 2192 197614 AsiAdmin phantom pts/1 Console 05:51:51 Apr 02 2010 2 3248 197615 wphaskett udt pts/2 192.168.1.51 05:54:32 Apr 02 2010 2 Dev (0)-> PORT.STATUS PID 2192 CALL.STACK Licensed(UDT+CP)/Effective Udt Sql iPhtm Pooled Total (24 + 1) / 25 3 0 0 0 3 Udtno Pid User UserType Port Last command processed 1 2192 AsiAdmin phantom 28101260 2 Dev (0)-> Am I missing something?
